(Top) Longitudinal TA ultrasound shows an immediate neonatal uterus (day 2). The uterus is prominent with a bulbous cervix and a
rudimentary body. The endometrium is seen as a thin, echogenic line, which may be due to stimulation by the residual maternal
hormones. (Middle) Longitudinal TA ultrasound shows a prepubertal uterus in a patient 8 years old. The uterus demonstrates a tubular
appearance with the length of the cervix nearly double that of the uterine body. (Bottom) Longitudinal TA ultrasound shows an early
pubertal uterus in a patient 12 years old. The body length of the uterus approximates the cervical length with the endometrium,
changing in appearance and thickness during the menstrual cycle. At this time, the uterine body grows dramatically until it reaches the
adult size.
